An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-16771 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.linecorp.armeria:armeria (Maven): affected from 0.50.0; fixed in 0.97.0\n- com.linecorp.armeria:armeria (Maven): affected from 0.50.0; fixed in 0.97.0\n- com.linecorp.armeria:armeria (Maven): affected from 0.85.0; fixed in 0.97.0\n- com.linecorp.armeria:armeria (Maven): affected from 0.85.0; fixed in 0.97.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-16771/ (Markdown: https://insights.sbomify.com/CVE-2019-16771/index.md)","id":"CVE-2019-16771","markdown":"https://insights.sbomify.com/CVE-2019-16771/index.md","name":"CVE-2019-16771","record":{"aliases":["GHSA-24r8-fm9r-cpj2","GHSA-35fr-h7jr-hh86"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java HTTP library","requires_auth":"none","summary":"Remote attackers can inject arbitrary HTTP headers via CRLF sequences in Armeria, enabling cache poisoning and XSS.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"armeria","vendor":"linecorp"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"Versions of Armeria 0.85.0 through and including 0.96.0 are vulnerable to HTTP response splitting, which allows remote attackers to inject arbitrary HTTP headers via CRLF sequences when unsanitized data is used to populate the headers of an HTTP response.
